**Henry**, Wednesday, April 25, 2012 at 6:58pmWe form 2 rt. triangles with a common ver. side:

Y = 50 m. = Ver. side.

X1 = hor. side of larger triangle(30 Deg).

X2 = hor. side of smaller triangle(60 Deg).

tan30 = Y/x1 = 50/X1.

X1 = 50/tan30 = 86.6 m.

X2 = 50/tan60 = 28.9 m.

d = X1 - X2 = 86.6 - 28.9 = 57.7 m. =

The distance between cars.
